Asteraceae · herb, root

Purple coneflower

Echinacea purpurea

Conflicting evidenceUse with caution

Mapped to conflicting prevention and treatment literature for seasonal URI. Products differ wildly.

Safety first

Asteraceae allergy. Theoretical concern in autoimmunity and transplant immunosuppression. Not a vaccine. Herb and root are different drugs.

Tradition vs trials

Traditional record. Plains North American use later industrialized in Europe. Commission E recorded aerial parts of E. purpurea.

Trial literature. Prevention and treatment trials conflict. Cochrane-type summaries are mixed. Species (purpurea vs angustifolia vs pallida) are not interchangeable.

Practical ranges

Educational ranges — not a prescription. Culinary use is not an extract.

  • herb juice / extract

    Commission E-type short-term adult ranges exist; products are not equivalent

    ESCOP / German Commission E / NCCIHEducational range only — not a prescription. A licensed clinician individualizes product, dose, and duration.

Pregnancy, nursing, children

  • Pregnancy. Short-term traditional use is recorded; this catalog does not treat that as clearance.
  • Nursing. Insufficient reliable data; avoid unless a clinician directs otherwise.
  • Children. Insufficient reliable data; avoid unless a clinician directs otherwise.

Contraindications

  • Asteraceae allergy
  • do not replace indicated vaccines or sepsis care

Key interactions

  • immunosuppressants · caution

    Theoretical; clinician conversation in transplant and autoimmunity.
